To all whom it may concern:

Beit known that l, Issac l/V. P. BU- CHANAN, a citizen of the United States, residing at Lebanon, in the county of Wilson and State of Tennessee, have invented new from with a view to promoting sanitary con ditions in barber shops and other public places, and this expeditiously so as not to entail delay in serving customers and without involving injury to the article or articles subject to the action of the apparatus notwithstanding the fact that utilization of a flame is the prime factor in the practice of the invention.

Another object of the invention is the pro vision oi an improved and highly eilic' means for producing combustion and directing the flame, the combustible and the products of combustion against the article or articles to be treated in such manner that a considerable portion of the combos tion talres place in intimate contact with the article or articles, thereby assuring thorough destruction of bacteria the complete removal of hair and hair oil from the article or articles.

Another object is the provision oil: a sirn pie, inexpensive and easily operated apparatus tor the purpose stated, and one capable of being embellished to such an extent as to enhance the finished appearance of a ban ber shop of high order.

To the attainment oi the toregoingthe invention consists first in my novel and advantageous apparatus, and second in my peculiar and highly efiicient'flame produc" ing means; it being understood, in this latter connection, that the said flame producing means per 86 may be used in any connection to which it is applicable without departure from the scope of my claimed invention.

Il n'the accompanying drawings which are hereby made a part hereof Figure 1' is a side elevation of the apparatus constitutini the best practical embodiment of my invention that l have devised.

- lg. 10 is a transverse section of said inei'erring by numeral to the said drawings and more particularly to Figs. 1 to 5 tnereor:

is the base of the apparatus. in addition to the said base 1 the aparatus comprises a pivot post The said post 2 may be attired to the base in any prei, the extension of the post downwardly through the base, and the mounting of a nut i on the threaded lower portion of the base as ell as the disposition of the said nut in a counter-sink 5 the underside of the base, these provisions being made in order that the post may be read ly disconnected from the base for the sake of com in the present and preferred embodiment the said element or holder is in the form of a horizontally disposed, revoluble platform;

the same being provided at its center with a sleeve 7, closed at its upper end and disposed upon and supported by and adapted to freely rotate about the post 2. On its perimeter the said platform is provided with knobs 8 through the medium of which it may be conveniently whirled at a high. rate of speed. At its upper side the said platform is provided with brush holders and a comb holder arranged in such relation that when properly placed the brushes and the comb to be treated will describe a triangle, as best appears in Fig. 2. The" brush holders are formed by a duplex clip 9 in combination with single clips 10 arranged in spaced relation to the duplex clip as appears in Fig. 2, all of said clips being suitably fixed to the upper side of the platform 6. The comb holder is made up of a body 11, of angular form in cross section, Fig. 1, and bracket arms 12 fixed to the body 11 and occupying the horizontal center thereof and having stops 13 at their outer ends. The brushes, indicated by 14: are readily placed in and removed from the clips described by vertical movement of the brushes, and yet there is no liability of either brush being casually displaced incidental to the rapid rotation of the platform. Manifestly a comb, indicated by 15 may be placed on and removed from the brackets 12 with the same facility, and without liability of the comb being casually displaced during rotation of the platform. It is essential to the successful practice of my invention when brushes and combs are to be sterilized for the combs and the bristles of the brushesto be made of metal, this because the sterilization and the cleansing of the articles involves the use of fire.

1 would have it understood at this point that the brushes I prefer to employ in conjunction with my novel apparatus are constructed in a manner clearly shown in Figs.

9 and 10, the brush shown being made up of a wooden head 16, wire bristles 17 a flexible layer 18, of rubber or like material carrying thebristles and arranged against the inner side of the head and a marginal plate 20, of angular form in cross-section, detachably connected to the head 16 through the ma- 7 dium of screws 19 or other suitable means and between which and the head the layer 18 is removably secured. Incidentally the" side portions of the marginal plate 20 serve to prevent charring of the edges of the head 16 and inthat way prolong the usefulness of the said head; and it will be manifest that by the utilization of the marginal plate in the relation described, the layer 18 and its set of bristles may be quickly and easily removed from the head when the layer deteriorates or becomes impaired. and a fresh layer 18 and its complement of bristles may be as readily attached to the head.

My invention contemplates the furnishing of a set of brushes in conjunction with the apparatus, and it follows from the construction described that the usefulness of.

the major portions of the brushes may be prolonged for an indefinite period, thereby contributing to economy in the practice of the invention.

Any suitable means may be employed for throwing flame against the brushes and the-1xcomb during the rapid rotation of the plat-- form '6, and when theflame is so directed:

against the comb holder 11 itwill be observed that the said holder will serve to conupon by the flame. llt will also be noticed here that the rotation of the platform filias' the effect of carrying each brush and "the" comb throughout the length thereof into the path of the flame so that there will be no liability after an operation, of any bacteria, hair, or hair oil remaining upon either brush or upon thecomb. The rapid rotation of the platform 6 has the further efl'ect of precluding melting or other injury to the comb or material injury to the flexible layers 18 of the brushes. j

While as stated, any means may be employed for throwing flame against the brushes and combs without departure from thescope of my claimed invention, I prefer to employ the means illustrated because of the simplicity and efliciency of said means and the facility with which the same may be operated. The said specific flame throwing means comprises a hydro-carbon receptacle 20, a wick 21 complementary thereto, ahy dro-carbon receptacle 22 which is shown as separate from the receptacle 20 though they might be in communication wiithout de-. parture from the spirit of my invention, an injection conduit 23 in communication with the interior of the receptacle 22, and a compressible bulb 2 1 connected through a-conduit 25 with a tube 26, which-in turn communicates with the injection tube 23 and in the ordinary well-known manner so as to serve the dual purpose, when the bulb is compressed, of displacing hydro-carbon from the receptacle 22 and atomizing the said hydrocarbon or commingling the same with air so as to form a highly inflammable spray. The scheme of my invention involves the 'ignition of the wick 21, the rapid rotation of the platform 6 with the brushes and comb there- 1 on and the rapid alternate compression and relaxation of the bulb 24, and when this scheme is carried out it will be manifest that during their movement the brushes and the comb will be bathed in fire; also, that because of the employment of the peculiar and advantageous flame producing and jetting apparatus described, a considerable portion of the combustion will take place in intimate Leashes contact with the comb and-the bristles of the brushes with the result that the said ele ments will be thoroughly cleaned and freed of bacteria, hair, and hair'oil. I prefer to employ grain alcohol as the hydro-carbon in the receptacle 20 and 22. I also prefer to affix the said receptacles to the base 1 in the manner shown at the right of Fig. 3, that is to say by providing the receptacles with dowels 30 which are let into seats 31 in the upper side of the base and are detachably fixed to the base through the medium of screws 32, counter-sunk in the underside of the base so as to permit of ready detachment of the receptacles when occasion demands.

The modification illustrated in Figs. 6, 7, and 8 embodies the base 1, the platform 6, and the flame producing and throwing means common to the apparatus shown in Figs. 1, 2, and 3. The said modification, however, is peculiar in its means for holding a brush and a comb upon the platform; the brush holding means being adapted for use in conjunction with a conventional handle brush 14: as shown. The brush holder of the modification is made up of opposed and spaced clips 9 fixedly connected to the platform. The comb holder of the modification is made up of opposed and spaced clips 11, and these latter are fixed to the platform and are so arranged relative to the clips 9 that when the comb 15 is in position for sterilization the said comb will rest coincident with the longitudinal center of the brush. Therefore, with a view to assuring thorough sterilization of the brush bristles and the comb throughout the length thereof I provide at opposite sides of the clips 9 the deflectors 40, best shown in Fig. 7 These deflectors are fixed upon the platform and are so disposed that at intervals during the rotation of the platform they will have the effect of spreading the flame impinged thereagainst toward the end portions of the settled bristles and the brushes of the comb.

The operation of the modified apparatus is the same as that before described with reference to the embodiment shown in Figs. 1, 2, and 3, and therefore it is deemed unnecessary to reiterate the same.

Having described my invention, what T claim and desire to secure by Letters-Patent 1s 1. The combination in a sterilizer, of flame-throwing means, and a movable holder for an article to be sterilized, arranged when actuated to present the article to the flame at intervals.

2. A sterilizer comprising a base, flame throwing means thereon, and a movable holder on the base for an article to be sterilized; the said holder being constructed and arranged whem actuated to present the article to the flame at intervals.

3. A sterilizing apparatus comprising a base, flame throwing means carried by the base, a platform carried by the base and mounted to rotate in proper proximity to the flame throwing means, and means on the platform for holding an article to be sterilized, whereby when the platform is rotated the article will be presented at intervals to the flame.

4. The combination in a sterilizer, of means to create a burning atmosphere, and means to rapidly move an article to be sterilized into and out of said atmosphere.

5. The combination in a sterilizer, of means to create a burning atmosphere, and revolving means to rapidly move an article to be sterilized through said atmosphere.

6. A sterilizing apparatus comprising flame throwing means, a revoluble platform arranged in proper proximity to the flame throwing means, and means on said platform for holding an article to be sterilized, whereby said article will be presented to the flame at intervals during the rotation of the platform.

7. A sterilizing apparatus, comprising flame throwing means, a revoluble platform in proximity thereto, a duplex brush holding clip on the platform, single brush holding clips on the platform in spaced relation to the duplex clip, and a comb holder carried by said single clips and made up of an angular body, and brackets carried by said body and constructed and arranged to prevent casual displacement of a comb.

in testimony whereof I aflix my signature. 10c
